Absent or undetected? Effects of non-detection of species occurrence on wildlife–habitat models
W Gu, RK Swihart - Biological conservation, 2004 - Elsevier
Presence–absence data are used widely in analysis of wildlife–habitat relationships. Failure
to detect a species' presence in an occupied habitat patch is a common sampling problem …

What are the issues with presence‐absence data for wildlife managers?
DI MacKENZIE - The Journal of Wildlife Management, 2005 - Wiley Online Library
Presence‐Absence data can be useful to wildlife managers in a wide variety of contexts,

Precision and bias of methods for estimating point survey detection probabilities
Wildlife surveys often seek to determine the presence or absence of species at sites. Such
data may be used in population monitoring, impact assessment, and species–habitat …

Modelling distribution and abundance with presence‐only data
JL Pearce, MS Boyce - Journal of applied ecology, 2006 - Wiley Online Library
Summary 1 Presence‐only data, for which there is no information on locations where the
species is absent, are common in both animal and plant studies. In many situations, these …
